Question

 In ∆PQR, Q = 90° , PQ = 4 cm , QR = 3cm, then Cosec R = ______​

Answer 1

Answer:

in a camp 500 men had provision for 27 days after

Step-by-step explanation:

in

Answer 2

Answer:

Step-by-step explanation:

pq=4

qr=3

rp=x

(pq)^2+(qr)^2=(rp)^2

4^2+3^2=16+9=25

rp=5

cosec R=hypo / opp

cosec R=5/4
